IPENNSYLVANIA, A CORPORATION OF PENNSYLVANIA LID-WRAPPING MACHINEApplication filed June 16,

Our invention relates to mechanism for wrapping lids of cigar boxes.

A purpose of our invention is to provide mechanismadapted to efficient,easy and inexpensive application of wraps to cigar box lids. i o i Afurther purpose is to register thetop of a lid of a cigar box with adesign upon the outside ofa glued lid wrap while the wrap is on a beltconveyer delivering to a wrapping machine and illumined from belowthrough the material of the conveyer.

In order to avoid having the belt become gradually opaqueto the light byreason of gradually accumulating glue from the glue machine, wepreferably isolate the section of conveyer at the illumined registrystation from the conveyer portion'that receives the wraps from the gluemachine.

A further purposeis to mount a raised gauge or stop along the lowerblock of a wrapping machine and to register a lid and wrap with theblock against the gauge, using the fingers ofthe operator to registerthe ends of the lid flush with the ends'of the stop.

A further purpose is to support the pressure exerted by the rear roll ofa wrapping machine operating to roll up the turn-up flap across thefront of the lid of a cigar box by the pressure of an opposingfront rollexerted against a stop gauge rigidly fastened to the lower form alongthe back of the lid. The gauge is preferably equal in height to thethickness of the lid so that the two rolls are simultaneouslyrespectively in engagement with the front of the lid and the outside ofthe gauge. I

A further purpose is to support the upturned front flap of a cigar boxlid abrush below the roll effecting the turn-up un- I til the turned upflap has been engaged by a turnin roll. a

A further purpose is to eifect the long side turn-in along the front ofa lid by rolling action, preferably mounting a resiliently downwardlypressed turn-in roll upon the so-called rear corner-lap plate holder barof a wrapping machine. 7

A further purpose is toefi'eot the end turnins of the lid of a cigar boxby rolling action,

preferably mounting resiliently downward ly pressed rolls uponth-eso-called turn-in plate holders of a wrapping machine. l

- A further purpose is to-eject wrappedcigar box lids from a wrappingmachine in a direction away from the operator, preferably passing themdirectly between finishing rolls.

These rolls smooth out unevennesses in the wrap and effect a moreintimate contact be-' ed to this machine, and disclosure upon awell-known machine makes detailed'description unnecessary as to manyparts that are in them elves not part of our present invention. TheUnited States patent most nearly corresponding with the complete Stokesand Smith machine is patent to Sonneborn, No. 1,646,563, issued October25, 1927, from whose illustration and description the operation of allof the machine shown, which isnot explicitly described herein, may beclearly understood. The embodiment shown is convenient and efiicient inoperation and illustrates particularly well the principles. in-

Referring to Figures 17 to 27, the wraps are applied to the tops of thelids and preferably do not extend quite to the back edges at the hinges,being cut away or terminating short of the edge. They lap over to thelid bottoms along the fronts and ends.

A narrow strip on the top of the lid adjacent the back edge is leftuncovered for an overlap portion of a linen hinge applied subsequentlyto the wrapping of the lid, and not part of the present invention.

The wrap (Figure 17) is preferably provided with edgelines for registrywith the front and endedges of the top of the lid, and

thelids are applied to the successive wraps at a registry station uponthe conveyer, strong illumination beneath the conveyer making visiblethe registry lines in order to facilitate placing the lids in properregistry with the wraps.

At-the wrapping machine the front flaps still down in Figures 18 and 19,are first turned up as shown in Figures 20 and 21, then turned in overthe bottom ofthe lid as shown inFigures 22 and 23. After this the endsare turned up as shown in Figures 24 and 25 and then turned in as shownin Fig- "ures'26 and 27.

7 Figures 1 and '2 show conveying mechanism for delivering the lids andwraps to the wrapping machine. This mechanism is normally operated bythe mechanism feeding wraps to any suitable glue machine, not

shown, which is preferably in turn controlled by'or synchronized to theoperation of the the wrapping cycle for one lid.

The glue machine and its feed mechanism are not shown and we have notshown the control from the wrapping machine. They are in themselves notpart of the present invention, which relates to novel operations andmechanisms to be embodied partly in a conveyer and partly in a wrappingmachine at the delivery end of the conveyer.

The illustrations of the conveyer and wrapping machine, with which weshow our invention embodied, are intended as conventionalillustrationsfor any conveyer and any wrapping machine to whlch our lnvention isadapted to be applied.

The conveyer and the registry station thereof (F z'gmes 1, 2 and 3) Thebelt conveyer 40 receives the wraps 41 from a suitable glue machine, notshown, and moves forward with intermittent steps that are of thesame-len th and of a length that is predetermined and usuallyadjustable. Each time that the wrapping machine 42 completes itswrapping cycle, a new wrap is delivered glue side up from the gluemachine to the belt conveyer, and the conveyer makes one of its forwardmovements advancing the wraps already on the conveyer toward thewrapping machine.

The successive wraps are thus placed glue side up along the conveyer atuniform intervals between the gluing and wrapping machines and come torest successively at the same definite positions orstations between thetwo machines.

lVe register the tops of the lids (m-the preferably glass, beneath thebelt conveyer and place a strong light beneath the plate, the plate andlight both being carried upon a frame structure 46 that is in turnsupported by, and preferably adjustable along side rails 47 of theconveyer;

The upper surface of the glass is even with the upper surface of theframe, the two surfaces presenting a firm horizontal sup- :port to thebottom of the belt conveyer so that the belt may present even support tothe successive wraps dur ng the application of the llds, and the frameand glass should be high enough to insure a section offiat belt over thewhole surface of the glass.

In practicethe upper surface of the plate and frame is preferably raisedsomewhat with respect to the opposite ends of the conveyer, as shown inFigure 2.

' The wraps (Figure 17) preferably carry a heavy printed line 48 forregistry around the front and end edges of the top of the lids The wraphas no flap at its rear side in 'hat'it must leave therear edge of thelid and desirably also a narrow strip along the top of the lid adjacentthe .rear edge uncovered for the application of a linenhinge. This hingeusually does not extend the full length of the lid and the rear of wrapis shown cutaway for the hinge at 41. The hinge and a finishing stripover it are applied subsequently to the wrapping operation of thepresent invention.

The lines 48 become visible when the wraps reach the registry plate, dueto the strong light beneath the plate, and make it very easy for anoperatorto secure exact registry of the lids upon the successive wraps.The operator places the lids top side down so that their outer edgesregister with the lines on the wrap.

It is old to register a box upon a glued wrap while the wrap is lyingupon a glass plate with a light beneath the plate. Hitherto, however,this has been done after the wrap has been removed from its beltconveyer. We avoid a removal from the conveyer by passing the conveyerover the glass making the light sufficiently strong to shine through thematerial of the conveyer and making the conveyer of material that willpermit this. 7

We have found that a strong light will satisfactorily shine through aconveyor of canvas or like material if the conveyer be reasonably freefrom glue. The conveyer shown comprises two sections to operate as abecome gradually opaque. g

The conveyer can be cleaned at intervals the belt 5 unit, connected bychain .and sprockets, 50. The first section 51 receives the successivewraps from a glue machine, not shown. r In practice we have found thatthe belt 51 becomes gradually coated withv glue by;

reason of glue dropping from wrap-stripping mechanism at the gluemachine and that. this glue coating'makes the conveyer by wire brushesso as to be fully operative for registration over the light but we havefound it more desirable to register upon a belt 52 kept free from glueby isolation from The belts of the adjoining sections pass overhorizontal parallel rolls 53 that keep the ad-' joining belts 51 and 52from contact yet are sufiiciently close to avoid danger of any of thewraps failing to pass from section to section.

The second belt 52 receives the wraps from the first belt and. bringsthem successively to rest over the light and registry plate 44 where anoperator registers the lids and wraps as stated. i i

The light and registry plate can be placed under the main belt but it ispreferable to iso-- late the portion of the conveyer at the registrystation as already stated.

l fe have found that it is desirbleto surtween the conveyers, thusavoiding any danger of glued wraps failing to pass from the first to thesecond conveyer.

W rapping machine The wrapping machine with which our invention isembodied is shown in Figure 3 which is a broken elevation partly insection and with many parts removed from the opera tors side of themachine. The conveyer sec tion 52 is broken away in front of theoperating mechanism of the wrapping machine at the delivery station 55(Figures 1 and 2) of the conveyer which is in front of the verticallyreciprocating plungers of the wrapping machine. 1

In the wrapping machine, a driving pulley 56 mounted upon the shaft 57is driven continuously in any suitable way and has clutch connection at58 with a sleeve 59. This sleeve surrounds the drive shaft and carries aworm 60 in continuous mesh with a gear 61 upon the lower end of a camshaft 62-.

ill of the wrapping movements of the machine are operated through themedium of cams upon this cam shaft which also controls the feed of wrapsto the glue machine as already described. The machine shown is ofwell-known type used in wrapping paper boXes and the like.

The upper plunger block 63 is carried upon the bottom of a plunger 64and the plunger .is adapted to reciprocate vertically, being guided insuitable stationary guide portions 65 of the frame of the machine.

The plunger 64: is positioned verticallyihy a cam-groove 66 around adrum 67 upon the upper end of the cam shaft. The connection is made bymeans of a roller 68 upon a rocker lever 69 and a link 70 between theleverand the plunger. The lever is pivoted at 71 in a suitable fixedbearing 72. p I

. A lower block 73 is mounted upon the head 74 of .the wrappingmachine." This head is a well-known standard'member of the wrappingmachine. It is resiliently pressed upwardly toward its upper position bya spring 75 and presents the lower block spaced beneath the upper blockinitially a sufficient dis tance from the upper block for easy insertionof a lid and wrap upon the lower block.

The wrapping operations take place during the downward travel of theupper block after it has engaged the lid upon the lower block whichmoves downwardly when the upper block moves down and subsequently risesas the upper block rises until the block again reaches its upperposition where it comes against a suitable stop and ceases to follow theupper block upwardly. The upper block continuues in its upward motionafter the wrapping cycle has been completed and finally stops in itsinitial position.

7 The successive lids are delivered top side down in front of the lowerblock at which point they are successively picked up by the operator andplaced upon the lower block preparatory to wrapping.

In transferring the lid with its wrap glued to its upper side (nowturned down) an operatorrconveniently lifts the lid by holding its endsbetween two fingers asillustrated in Figures 31 and 82, the end flaps ofthe wrap at this time extending outwardly beneath the fingers of theoperator.

The operator after raising the lid and wrap and placing it on the lowerblock pulls the lid forwardly against a raised gauge 76 along the frontof the block, using the ends 77 of the raised portion to gauge thelongitudinal position of the lid. At each end the corresponding fingersimultaneously overlaps the raised portion of the block and the adjacentend portion of the lid.

After the lid and wrap have been put to place on the block the operatorstarts the wrapping cycle by moving a suitable lever 78 of the machine.

The upper block presents a surface considerably smaller than that of thelid while the lower block presents an upper surface having outeredgesregistering with the outer edges of the top ofthe lid (now down).The upper block descends upon the lid registered upon the lower blockand clamps it to place between the upper and lower blocks againsttheretractive force of the spring 75.

The successive wrapping operations are shown in Figures 18 to 27'. V

The front flap 7 9 is first turned up while passing the lid and blocksbetween the usual rolls 80 and 81, (Figures 4 and 5), the front flapbeing presented to the rear side of the machine.

The front roll 81 rolls up the front 82 of the lower block and theoutside of the gauge 76 while the rear roll rolls up the rear '83 ofthelower block and the front flap 79. In this way the pressure of therear roll. upon the rear of the block is balanced by a correspondingequal and opposite pressure of the front roll. r

The height of the gauge 76 is preferably the same as the thickness ofthe lid in order that the two rolls may have the same simultaneousperiods of engagement.

W'e dispense with the wiping brushes normally carried above front andrear rolls but mount a brush 84 somewhat below the rear rollypreferablyupon the holder 85 of the rear roll.

This brush 84 engages the upturned front flap after the flap hasipasseddown from the rear roll and maintains engagement therewith until thefiap is engaged by a turn-in roll 86.

\Ve mount a turn-in member for the front flap as a roll 86 upon thecorner-lap plate holder bar of the prior art, resiliently pressing thisroll downwardly.

The blocks and lid after moving downwardly between the front and rearrolls 80 and 81 come to rest in the position shown in Figure 6 and atwhich position the cornerlap plate holder bar of the prior art carryingthe turn-in roll 86 moves inwardly to effect turn in, rolling the upperportion of the turn up lap 79 down uponv the bottom. of the lid.

After the turn-inroll'mounted upon the corner-lap plate holder bar hasmoved in and while it is still at its inner position the blocks carryingthe lid and wrap again move downwardly under the action of the cam 66,roller 68, rocker arm 69 and link 70. This downward movement carries theblock and lid between the end turn-up brushes 87 and the end turn-uprolls 88, both of the prior art to come to rest in position for theoperation of the end turn-in.

We mount end turn-in rolls 89 upon the end turn-in plat-e holders 90 ofthe prior art.

' These rolls move inwardly and again outwardly to effect a rolling endturn-in while the blocks are in their second position of rest.

After the end turn-in operation is complete 7 and the turn-in rolls havemoved back out of the way, the blocks may atonce start to rise. In themachine under illustration however, the blocks and wrapped lid may movefurther down before beginning to rise for adaptations to box wrappingoperations not used in the present invention.

when rising, the upper block is lifted by the upper plunger and thelower block follows under the upward pressure of the spring 75 until itreaches its upper position at which point it ceases to rise, the upperblock movmg on up out of the way leavlng the wrapped v lid upon thelower block.

Before the cycle is complete, and after the bring the wrap and lid intomore perfect and 2U: uniform contact.

From? turn in (Figures 5" to The front turn-in mechanism is an importantfeature of our invention and is shown as a roll 86 resiliently pressingdownward. The roll mechanism is mounted upon the socalled rearcorner-lap plate holder bar 94 of the Wrapping machine of the prior art.The front corner-lap plate holder bar of the prior art is not used andnot shown.

In the wrapping machine of the prior art a rocking member 95 (Figure 3)carries a suitable roller 96 operating. in a cam groove 97 to effect theinward and outward move ments of the corner-lap plate holder bars. Therocker 95 is linked to a secondary rocking member 98 that is in turnlinked at 99 (Figures 3 to 8 and 30) to a sliding member 100 carryingthe bar 94 carrying our front turn-in mechanism.

The sliding member 100 comprises horizontally spaced rods 101 and 102rearwardly extending from a plate 103 that is rigidly fastened to thecorner-lap plate holder bar.

The rearwardly extending rods have sliding bearing through suitableperforated lugs 104 of which one only is shown.

The link 99 to the rocker memberis pivotally connected at 105 to a crossmember 106 between the rods 101 and 102. v The cross member is rigidlyfastenedto these rods and adjustable longitudinally along them, as in.

the prior art.

Our front turn-1n mechanism comprises the roll 86 journaled in theendsofthe for-i wardly extending arms 107 of spaced bell crank members 108which are pivoted at 109 to blocks 110 fastenedto the rear'corner-lapplate holder bar. 7 V

Downwardly extending arms 111 of the bell cranks stop against therespective forward faces of the blocks and are springpressed inwardlytoward engagement with these facesby individualsprings 112 stretchedbetween suitable anchors 113 and 114 respectively upon the blocks andlower portions v ofthe arms. v

Mounting the turn-in roll mechanism upon the corner-lap plate holder barof the prior art is newandparticularly advantageous.

Endtumt-z'n mechanism (Figures 5. and!) i013) i '1 .I 'We effect: theend turn-ins by resiliently downwardly pressing rolls mounted upon theend turn-in plate holders of the prior art.

In the machine of the prior art the turnins have been moved inwardly andoutwardly by means of cam 115, roller 116, rocker lever 117 pivoted at118'to a fixed part of the machine and linked at 119 to verticallyreciprocate a central sleeve 120 surrounding the lowerportion of thelower plunger 121.

The sleeve 120 has oppositely extending i arms 122 which carry verticalrods 123 linked at 124 to rocker arms 125 that are in'turn linked at 126to tl1e'turn-inplate holders 127' of the prior art. p k 1 r Thehorizontal reciprocation of the turn-in mechanism 'of the prior art isthus effected by the vertical up and down movements of the centralsleeve120 which is in turn effected by the rocker arm 117 and cam 115. p

The. plate holders 127 comprise slides having horizontally spaced rods128 extending outwardly I from blocks 129 to which we fasten our endturn-in roll mechanisms.

The block 129 is pivotally connected at 130 to the link 126 of therocker 125 and the rods operate in suitable bearings, not shown, but

generally 'similar to the bearings 104 of the front turn-in mechanism(Figures 4 to 6).

Our end turn-in rolls have journal support at the ends in lever members131 which are pivoted at1'32 toa supporting block 133 fastenedat 134 tothe holder 129 of the prior art. The outwardly extending arms 135 of thelevers. 131 are recessed to receive stop pins, 136 which projectoutwardly from the ends of the blocks 133 (Figures 12 and 13) and arespring-pressed to contact with these pins by fiat springs 137fastenedupon the bottom of the blocks (Figure 13)..

The'new feature of this mechanism comprises the advantageous rollmechanism mounted upon the turn-in plate holders of the prior art.

The end turn-in operationstake place at the second position of rest andcomplete the wrapping operation at the wrapping machine. I The wrappermachineof the prior art is usually built to give the plungers a r shortadditional downward movement and we prefer, to let the machine have thisunnecessary further downward travel of the plungersfor the sake of theresultant adaptation of the machine to box wrapping.

Ejector mechanism (Figures 3,;5,"16 and $2.9) After the end turn-inoperations have been completed and with or without additional downwardmovement of the plungers, the plungers rise until the lower block isleft in its initial position, the'wrappedlid lying on the lower blockback of the gauge 7 6 and the upper block moving on up out of theway.

Ejector mechanismstriking through the recess 92 in the front gauge 76knocks the.

wrapped lid rearwardly into a position at which it is taken hold of bythe finishing rolls 93 and 93 and passed'between'these rolls.

lVe mount a rocker 141 upon a'vertical pivot 142 upon a fixed part 143of the machine in front ofthe lower block and link one end of thisrocker to the ejector plunger 144 at 145 and the other end at146 to thehead 147 of the ejector of the prior art which has a spring-releasegoverned by a cam upon the main camshaft.

"We use the same spring release for ej ecting the lid that was used inthe prior art but. eject rearwardly instead of laterally.

The ejector plunger 144 operates in a suitable guide 148 in line withthe recess 92 of the gauge.

lVe find if the blows of ejector plunger are either too hard or toolight the lids will not be taken hold-of by the finishing rolls.

As the wrapping machine operates upon variant types of lids we find'itdesirable to make the strength of blow struck by the ejector plungeradjustable and maydo this by providing a succession of perforations 149to receive the pivot connection 150 between the plunger 144 and thelinkmember 145.

The lid ejection is in a direction away from the operator because wemount the'finishing rolls at the far side of the machine. lVe thus ejectthe lid in a direction at'right-angles to the line of the operation ofthe ejector plunger of the prior art. w

The finishing rolls (Figures 3, 28, 2.9, and 30) revolve continuouslyand may be suitably driven by gearing from the drive shaft 67. of themachine, or, as illustrated in Figure 3, may be provided with a separatemotor drive.

In Figure 3 the shaft 153 of the lower roll 93 carries a pulley 154which is connected by belt 155, pulley 156, shaft 157, pulley 1'58, belt159 and pulley 160 to the shaft of an auxiliary motor 161.

The lower roll is journaled in fixed bearings 162 and the upper roll isjournaled in bearings 163 that are spring-pressed downwardly at 164 tomaintain friction contact between the rolls, the lowerrol'l'driving-the' upper roll by friction, the upper roll rotating as anidler only by reason of engagement with lts mate, or by reason ofengagement with a finished lid passing through between the rolls.Optionally the rolls are geared together.

The rolls deliver the finished lids away-j from the machine to asuitable inclined chute 165. V e Cycle of operation A desirable cycle ofoperation when the invention is embodied upon a wrapping machine of thetype shown is indicated diagrammatically in Figure 33. 7

Some of the operations indicated upon the cycle may beconsiderablymodifiedif a different type of wrapping machine is used, andsome of the movements indicated are unnecessary during the wrappingoperation of the invention, the movements being taken from a well-knownmachine of the prior art, and being in some instances such as to adaptthe machine of the prior art to operations foreign to the presentinvention. I

Vertical ordinates on this chart representsimultaneous positions of therespective parts throughout a single cycle, the common abscissaerepresenting time and the respective parts being shown by suitablenotations on the different curve lines which are also lettered forgreater convenience of reference. The different movements are away fromand backto initial positions, some of these move- 'ments being down andup and others horiabove the extending end flaps lays it upon the lowerblock, draws it forward into contact with the raised portion 7 6 of theblock (a registry gauge) and secures longitudinal registry bysimultaneously passing the fingers from the ends of the lid across theends of the raised gauge.

The clutch of the wrapping machine is then released at 170. The upperblock now some distance above the lower block, moves downuntil at thepoint 171 it engages the upwardly presented bottom of the lid upon thelower block, clamping the lid between the opposing rubber covered facesof the upper and lower blocks, and starting the lid and lower block uponits downward travel agamst the upward force of thespring 75, toultimately come to rest after passing between the front and rear rolls81 and respectively at the point 172. a

In the passage between the front and rear rolls (Figure 4) therearwardly projecting front flap is rolled up the front of the lid bythe rear roll, the resilient pressure of this roll against the lid beingbalanced by an equal and opposite resilient pressure exerted by thefront roll which rolls up the outside of the gauge 7 6 at the same timethat the rear roll is turning up the front flap.

When the upper and lower blocks come to rest at the point 172 both therear roll 80 and the supporting brush 86 are above the upper edge of theturned up front flap 7 9 and the front turn-in roll 86 mounted upon thecorner-lap plate holder bar of the prior art is in position to moveinwardly to effect turn-in. The supporting brush 84 has maintainedcontact however with the front flap until the flap is in position to besupported by the turn-in roll 86 (Figure 5).

At the point 178 the turn-in roll 86 mounted upon the rear corner-lapplate holder bar of the prior art begins to move inwardly (Figure 6) toeffect turn-in and turn-in is complete at or before the point 17 4 atwhich the turn-in roll is at its innermost position, before the nextdownward movement of the blocks.

At the point 175 the upper and lower bloclrs begin to travel downwardlyto pass between the end turn-up brushes 87 and end turn-up rolls 88(Figures 9 and 10) which turn up the end flaps of the wrap, the blockscoming again to rest at the point 17 6.

The end turn-in rolls with the blocks at rest move inwardly to effectend turn-ins between the points 177 and 178 (Figure 11) and move againoutwardly between the points 179 and 180.

The downward travel of the blocks shown between the points 181 and 182,as well as the subsequent movements of the turn-in rolls indicated alongthe curve E are for purposes foreign to the present invention, also theperiod of rest between the points 182 and 183 before the blocks begin tomove upwardly is to allow time for operations foreign to the presentinvention.

At the point 183 the blocks begin to rise, the lower block havingreached its upper position at the point 184.

Between the points 184 and 185 the lower block is stationary and theupper block is rising reaching its upmost position at the latter point.

At a point 186 the kick-off (lid ejection) takes place the time of thekick-off being sufficiently after the point 184 to permit the upperblock to be out of the way. The kiclnoff or ejector mechanism deliversthe wrapped lid to the finishing rolls. The clutch opens at 187 and thecycle is complete.

While we have illustrated our invention applied to wrapping cigar boxlids it will be noted that various features of our inven- In view of ourinvention and disclosure variations and modificatlonsto meet indivldualwhim or particular need Wlll doubtless become evident to others skilledin the art,
